The crossover — of sorts — will take place duringApartment 23's Halloween episode, in which we'll learn that June (Dreama Walker) is a Happy Endings fan. "June makes a video on her iPhone," Apartment 23 creator Nahnatchka Kahn tells us, likening the video to the ones 'shippers make for their favorite TV couples. "She does it for Chloe [Krysten Ritter] and one of the Happy Endings guys."

In the same episode, Chloe will meet her new love interest, played by Ben Lawson, which is the catalyst for the video. "She makes the fan video to show Chloe that love is possible," Kahn says.
